drtravels,

I think the comment about the service received vs. fare paid was not complaining about the different levels of service between first and coach. The issue is that once you are seated in first, the level of service should be the same, regardless of whether you paid full fare, got an upgrade, are using a free award ticket, or bought a discount premium ticket from the airline during a fare sale. Some airlines are notorious for providing different levels of service to passengers in the same premium cabin based on the fare they paid. Others don't even list this information on the passenger manifest, making it impossible for the flight attendants to do this, even sub-consciously.
